Half A Tank is a summer-long quest to find images and stories of people whose lives have been altered by a flattened economy. Starting from home in the D.C. suburbs, Theresa Vargas and Michael Williamson are traveling around the country to experience how people are coping, struggling, even flourishing as we all reconsider how we live. Please share your reactions and experiences in the comment sections that follow each post.

Theresa Vargas is a native of San Antonio who, until now, has had only two memorable road trips: Hitchhiking through South America and riding in the back of a pick-up truck from California to Texas at the peak of summer. She came to The Post in 2006, where she has covered crime and education. She lives in Virginia.

Michael Williamson is a Pulitzer Prize-winning photographer. He was born in Washington, D.C. and lived in 37 other places before coming back to work at The Washington Post in 1993.
